APPARATUS FOR SUPPLYING FEED-WATER 'TO BOLERS.

SPECIFICATION forming part of Letters Patent No. 514,468, dated February 13, 1894.

Application led May 22, 1893. Serial No. v475,060. (No modali) To all whom t may concern:

Be it known that we, GEORGE ERNEST HUD- SON and GEORGE SANDERSON, both residing at Scarborough, England, have invented new and useful Apparatus for Supplying Feed- Water to Boilers, of which the following is a specification.

The object of our invention is to remove the larger portion of the grease, lime, and other impurities from the exhaust steam of non-condensing engines, and to utilize the water obtained therefrom, While still in its heated state, as feed-water for the boilers of such engines, whereby the deposit of mud or incrustation of the boiler is prevented, and less fuel is required to produce and maintain the necessary supply of steam.

In carrying out our invention We conduct the exhaust steam direct from the cylinder of the engine through a pipe connected to a steam tight chamber, which is provided with a second exhaust pipe for the escape of uncondensed steam, and an outlet pipe at the bottom. In this rst chamber the larger portion of the 'oil or grease contained in the steam, Whether volatilized or carried over mechanically by the rush of steam, is deposited, mixed with Water, and from thence is drawn off by means of the outlet pipe before mentioned. The exhaust pipe leading from this first chamber conducts the main volume of steam to a second chamber Where one or more jets or sprays of cold Water meet the inrushing steam, immediately lowering its tempera-n ture and condensing it. rIhe hot Water thus obtained falls into the lower part of the second chamber from whence it is drawn off by means of pipes for use as required.

When a jet of hard water, or Water containing lime is used for condensation in t-he above named apparatus, a portion of the lime combines with the small residue of oil or grease in the steam, and forms a deposit which is immediately precipitated to the bottom of the chamber, where also is deposited the lime set at liberty in the spray of cold water which comes in contact with the heated steam. These lime deposits form a solid mass at the bottom of the second chamber, for the removal of which deposits a mud-hole is provided in a convenient position. lt is found in practice that the addition of the Water used for condensation to that formed by the condensation of the exhaust steam, produces a larger volume of hot Water than is necessary for the purpose of supplying the boiler. The surplus may therefore be utilized for Washing, dyeing, and other purposesin Which asupply of heated and purified Water is essential. An escape pipe'from the second chamber carries oil any surplus steam into the open air and prevents any possibility of back-pressure.

In order to enable ourinvention to be fully understood We will proceed to describe the same with reference to the., accompanying drawing in which r-The drawing represents a sectional elevation of a form of our condensing and purifying apparatus, in which the second chamber is fixed above the first.

The exhaust steam pipe A from the engine, enters the side of the iirst chamber B B, and in this chamber the main portion of the oil and grease becomes separated from the steam, and is deposited upon the sides, or falls direct to the bottom, from whence it is drawn on, mixed With a certain proportion of Water, by the valve N. A mud-hole M is also provided, through which the chamber may be cleaned out. From this chamber B B the steam passes to the second chamber C C by the pipe D, in entering which chamber the steam is met by a jet of cold Water from the pipe E, which jet immediately condenses the steam, and causes it to fallas hot Water to the lower part of the chamber, from whence it is Withdrawn by the feed-pipe F.

The deposit of lime and other impurities is representedat K, which deposit is removed periodically through the mud-hole L. An overow pipe is represented at H, and an escape pipe at J which conducts into the open air anysurplus uncondensed steam.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, We declare that what We claim is The described apparatus for supplying puried and heated feed water to boilers of noncondensing engines, consisting of the combination of the following features: the lower IOO and upper compartments B. C. separated byv C., and a feed pipe F. below such overflow to io a closed partition or bottom, pipe A. leading carry off or Withdraw from the apparatus the from the engine to the bottom compartment, hot Water of condensation.
